(RNS) Only seven contenders will be on the main stage for Fox Business News’ broadcast of the sixth GOP 2016 presidential debate Thursday (Jan. 14) — almost all well-known for taking strong stands on faith in hopes for a boost from devoted viewers.

The December debate was the third-most-watched one in debate tracking history, according to CNN. The theme of this week’s debate will be economic policy, with managing editor for business news Neil Cavuto and global markets editor Maria Bartiromo asking questions.

Watch for candidates to tie their economic views to biblical morality. Most of the debaters are making a strong push for religious viewers, known for high turnout on Election Day.

Former Florida Gov. Jeb Bush is sliding in the poll but still made the main-stage cut, just ahead of Kasich, by a statistical wing and a prayer.

Carly Fiorina and Sen. Rand Paul have fallen to the second-tier debate. Paul, still hoping to be reinstated to the main stage, has said he won’t participate. But Fiorina will join former Arkansas Gov. Mike Huckabee (the only Southern Baptist pastor in the race) and former Sen. Rick Santorum, who once said the idea of church-state separation made him want to vomit.
